FR-D700 Series – Variable Frequency Drives

FR-D700 is Mitsubishi Electric’s class-leading range of micro drives.

FR-D700 Series | Inverters from Garland Instruments

Suitable for a wide variety of general purpose motor speed control applications, the FR-D700 was built from the ground up using custom components and has earned an enviable reputation for durability and dependability in adverse environments.

Key Benefits

Highly compact design – Reduced installation footprint

3 Year warranty – Extra peace of mind

Safety drive capability – Eliminates the need for an extra contactor for operator safety

Built-in MODBUS® RTU communications – Seamless integration into control systems

60:1 speed range – Fast acceleration of high inertia loads

Bookshelf mounting capability – Increased installation density allows smaller panel sizes

Built-in dynamic braking circuit – Allows for simple installation of brake resistors for heavy deceleration

Failure safety with self-diagnostics

This inverter actively monitors its own functional safety. If, for example, the fan rpm decreases to 50 %, a pre-alarm is triggered. An internal measuring program monitors the ageing of the capacitors and an operating hours counter enables the operator to plan the best time for servicing. Protection and overload functions like the phase failure monitoring system for both the input and output circuits ensure trouble-free operation.

Additional energy savings

The FR-D700’s OEC function helps to further optimize current and hence power consumption of the motor. The result is an additional decrease in energy requirement compared to a conventional inverter.

Long service life

The FR-D700 is designed for a service life of over 10 years. This is made possible, among other things, by high-performance heat- resistant capacitors, cooling fans with sealed bearings and special lubricating grease. The flow of cooling air comes into contact only with the heat sinks and not electronic components. This ensures that no dust or dirt can collect on the components. The circuit boards are protected against aggressive environments with single or double layer conformal coating – another feature that ensures longer service life.

Upgraded functional scope

To protect both staff and valuable machinery, the FR-D700 has innovative functions that enable it to respond with great sensitivity to a variety of external factors.

Safety function “Safe Torque Off” (STO) according EN 61800-5-2

The “Safe Torque Off” function (STO) disconnects the power fromthe motor and prevents an unexpected re-start. Thereupon the motor coasts to a halt. Compared to the traditional technology with contactors, this integrated Safety function reduces the effort in hardware, wiring and maintenance and offers higher performance and lifetime.
